The high potency of PBL relative to CW blue light makes it a suitable antimicrobial for suppressing bacterial growth in biofilms as wel...

AbstractPurpose of ReviewStaphylococcus aureus is the primary pathogen responsible for osteomyelitis, which remains a major healthcare burden. To understand its dominance, here we review the unique pathogenic mechanisms utilized byS. aureus that enable it to cause incurable osteomyelitis.Recent FindingsUsing an arsenal of toxins and virulence proteins,S. aureus kills and usurps immune cells during infection, to produce non-neutralizing pathogenic antibodies that thwart adaptive immunity.S. aureus also has specific mechanisms for distinct biofilm formation on implants, necrotic bone tissue, bone marrow, and within the osteo...

The present study is the first to clone a galectin gene (SpGal) from S. paramamosain, by the rapid amplification of cDNA ends technique based on expressed sequence tags. The full-length cDN...

This study surveys the clinical relevance of the nasalStaphylococcus aureus colonization status on intensive care unit (ICU) –acquiredS.aureus infections and compares molecular characteristics of isolates from the nose and infectious sites. The 390 patients included comprised 278 non-carriers and 112 carriers. Among the carriers, 56 were decolonized with mupirocin. Decolonization was verified through a second (negative) culture. Spa typing and virulence gene profiling were performed for all isolates. Twenty sixS.aureus infections were detected in the carriage group and 20 in the non-carriage group. Eighteen of these ...

This study underscores the capacity of human DC to discriminate between live and inactivated S. aureus and, further, indicates that DC may represent a valuable experimental setting to test different inactivation methods with regard to the retention of S. aureus immunoregulatory properties. These and further insights may be useful for the development of novel therapeutic and prophylactic anti-S. aureus vaccine strategies.

ConclusionEthyl acetate &Water extracts have represented potent activity against Salmonella typhi, Escherichia coli, &Staphylococcus aureus bacteria as well, provided cytotoxicity against tested cancer cell lines. These results can be explored to identify individual phyto-molecules from the extracts for anticancer &antimicrobial potentials to identify new phytomedicines.
